Square (Reef) Knot
Square Knot, also known as Reef Knot, is used for binding two ropes together. This is one of the first knots all people learn when tying - shoe laces. Unfortunately, this is not a safe knot.
Square knot should not be used when safety is critical due to its tendency to slip, to come undone etc. But, it is suitable knot for many uses, especially if they are not under (heavy) load and when more secure versions can be used.
